Evaluation of microbiological and physico‐chemical parameters of retail ready‐to‐eat mono‐varietal salads
2019
An integrated microbiological and physico-chemical approach was applied to evaluate the decay of mono-varietal ready-to-eat escarole (Cichorium endivia var. latifolium) and red chicory (Cichorium intybus L. var. foliosum Hegi) during refrigeration. Total mesophilic microorganisms, including pseudomonads, and total psychrotrophic microorganisms were detected at high numbers in all samples just after packaging and at the expiry date. The dominant microbial populations analyzed by classical culture-dependent methods belonged to Pseudomonas and yeasts. Illumina sequencing identified Janthinobacterium lividum and Pseudomonas veronii as main species. Regarding the physico-chemical quality between…
Shelf life evaluation of fresh-cut red chicory subjected to different minimal processes
2018
Abstract Microbiological, chemical and physical parameters of minimally processed red chicory (Cichorium intybus L.) subjected to two different transformation processes were investigated. A classic ready-to-eat (RTE) process (P1) and a production without cutting (P2) were monitored during refrigerated (4 °C) storage (15 d). Total mesophilic microorganisms, total psychrotrophic microorganisms and pseudomonads were detected at the highest cell densities in all samples. Presumptive Pseudomonas population dominated the cultivable microbial community of RTE red chicory and were characterized genetically. Twenty-two randomly amplified polymorphic DNA (RAPD) types were investigated by 16S rRNA gen…
Effects of continuous and rotational grazing of different forage species on ewe milk production
2012
Abstract The aim of this research was to evaluate the effects of continuous and rotational grazing of different forage species on milk production in ewes. The forage species were chicory (Cichorium intybus L.), a mixture of oat (Avena sativa L.) and berseem clover (Trifolium alexandrinum L.), and sulla (Hedysarum coronarium L.). Forty ewes were divided into 5 groups, and subjected to one of the following treatments: continuous grazing on chicory, continuous grazing on the mixture, continuous grazing on sulla, rotational grazing on the mixture, or rotational grazing on sulla. Among the species continuously grazed, chicory showed a lower biomass than the mixture, or sulla. Ewes grazing chicor…
Microbial Ecology of Retail Ready-to-Eat Escarole and Red Chicory Sold in Palermo City, Italy
2019
Background: Ready-To-Eat (RTE) foods include any edible food that is commonly consumed raw. This study aimed at evaluation of microbial ecology of retail RTE escarole and red chicory sold in Palermo city, Italy. Methods: A total of 32 mono-varietal RTE samples, including escarole (n=16) and red chicory (n=16) samples were obtained from Palermo, Italy. Both RTE vegetables at expiry date were analyzed to quantify spoilage bacteria, pathogenic bacteria, and yeast. All different colonies were isolated and identified on the basis of phenotypic characteristics and genetic polymorphisms by random amplification of polymorphic DNA-Polymerase Chain Reaction (PCR) and further genotype by sequencing th…
Germplasm evaluation to obtain inulin with high degree of polymerization in Mediterranean environment
2020
Long-chain length (DP) inulin-type fructans show pronounced beneficial effects to colon microbiota. In the past, cardoon roots for inulin production to fortify spaghetti gave very good results, but their harvest requires high costs. The aim of the work was to evaluate different types of inulin, extracted from cardoon roots and buds, topinambur tubers and chicory roots local populations in order to identify crops more suitable for high DP inulin production in Mediterranean environment. The inulin amount resulted in 115 (chicory), 390 (cardoon) and 550 g kg−1 of d.m. (topinambur). Both in cardoon roots and in topinambur tubers the DP was very high. With the aim to produce a functional food, s…
Survey of antibiotic resistance of Pseudomonas isolated from fresh cut red chicory (Cichorium intybus L., Asteraceae)
2018
The present work was carried out to investigate the safety aspects of minimally processed red chicory (Cichorium intybus L., family Asteraceae) regarding the antibiotic resistance of Pseudomonas Migula, 1894 populations (Bacteria Pseudomonadaceae). The Pseudomonas strains tested for their characteristics were previously isolated from experimental monovarietal salads prepared with two different processes, a classic ready-to-eat (RTE) process and a process with entire leaves, and stored under refrigeration (4 °C) up to 15 days from production. Due to their dominance over the microbial community, Pseudomonas strains were better characterised for their undesirable features that might be exerted…
